Here's a visualization of its orbit, Earth in green, object in teal: http://orbitsimulator.com/gravitySimulatorCloud/yr/gsim2023....

It passed about 9 hours ago.

Oops, thoughtless basic error in posting something quickly. Good note.

It was first seen on August 12, midday UT1. About a dozen observations.

   ZTm0038\* C2023 08 12.49542 06 32 33.23 +15 57 35.5          18.86rUNEOCPI41

Is the first entry, and asterisk-marked, on https://cneos.jpl.nasa.gov/scout/#/object/ZTm0038 at the bottom, in the Observations section. Unusual (new to me) format. Appears to me, first guess to read:

   [object] [yr] [m] [day.time-decimal] [position] [elevation-angle]   [observatory]

Likely oriented relative to the plane of the ecliptic, and absolute direction relative to Earth at time of observation.

I don't know what I'm talking about. Just giving best-guess interpretations.
